Ok guys I have a really simple question.
I currently have a 560ti OC a 1GB version. I hear this and that on how 1GB is limiting and so on and so forth.
I seem to have started experience its limitations.

I have some mods installed for Skyrim and they are mainly HD texture mods and stuff like that, and after playing for a while Im guessing the vram begins to limit out and fps drop and the game starts to stutter and lag.

My question is, is it time to look for an upgrade? Or would picking up another 560ti, even another 1Gb version, help me out at all? I know that 560Ti's SLI do better than a single 580, but is that a dumb choice because the 1Gb will still be my limiting factor?

I am aware of 7970 coming out tomorrow, but that may be out of my reach $$ wise, and I love nvidia's cuda because I encode a lot and cuda helps a lot.

you should try to monitor the VRAM using GPU-Z before sayin that 1Gig isn't enough, are you sure of that ?

Honesty no, not entirely sure of that, going by input from others. It has been stated that if you are using HD textures and such on skyrim especially a few of them, after a while it uses up the 1Gb of vram.

I will attempt to watch gpuz and check the vram., but what if it is limiting it?
change cards of sli?

If you're getting what I was getting, just Alt-Tab out of Skyrim, and come back in. I was getting some weird thing where upon entering an area (from fast travel, or just leaving a building) I would get really bad stutter and my frames would drop drastically for no reason. I Alt-Tab and when the game comes back up, it's smooth again. This was with like 8GB of texture mods installed as well.

ok cool ill try that out.

Thanks for the input guys. Not too sure what Ill do yet, but from what im getting out of it is that the 1gb of vram may not be affecting me much.
